Good for you. You are correct, technically, but trying to explain to
the average user that /certain/ OSs /can/ run under this program on
one type of CPU but on another type of CPU it can run any OS is asking
Bear in mind we are replying to a thread started by an OP who does not
know the difference between QEMU and KVM. I think that in your efforts
to make the answer more technically correct you are muddying the
waters and making said answer less clear, less helpful and less
